Abstract

The invention discloses functional leather with a super-hydrophobic self-cleaning surface coating. The functional leather comprises a substrate, a hydrophobic coating and a plastic surface layer which are mutually laminated; the hydrophobic coating comprises the following raw materials of hydrophobic paste and fused resin; and the plastic surface layer is prepared from the following raw materials of ETFE, perfluoroalkylate and polyvinylidene fluoride. The functional leather has the beneficial effects that waterborne polyurethane resin and superfine modified micronized polyethylene wax are used as the hydrophobic paste, then the fused resin and the hydrophobic paste are combined to form a hydrophobic layer, and then the ETFE is used as a main raw material to synthesize the plastic surface layer, so that the synthesized artificial leather has outstanding hydrophobic capacity firstly and is relatively compact and very good in wear resistance secondly; and thirdly, the fused resin and the hydrophobic paste are separately manufactured and molded and then are connected through hot melting, so that the structural compactness is better, and the obtained artificial leather is closer to natural leather and has better performance.

Description

Technical field [0001] The present invention relates to the field of clothing, in particular, relates to functional leather having a superhydrophobic surface of the coating self-cleaning. Background technique [0002] A leather appearance, feel like leather and plastic products used in place thereof. Usually end of the base fabric, and plastic coated with a synthetic resin added is made. At present, there are two types of synthetic leather PVC artificial leather, PU. Existing benefits include leather with soft, comfortable, beautiful and durable, warm and strong, has a moisture permeability, good color fastness, etc., if coated with a special substance, also waterproof. Meanwhile leather also has its drawbacks, whether it is breathable, moisture or abrasion resistance inferior to natural leather, and thus poor comfort of clothing made, or after a number of rubbing a long time, the coating may flake off the surface of the plastic, exposing the base fabric, so that leather-destruct...
